No, it won't kill the engine. Grass in the pullstart is just an issue that everyone gets with largescale RC. Grass will reduce the cooling tho which can lead to issues if it gets above about 130 centigrade so you need to make sure it doesn't get totaly blocked. If you are wooried, just whip the plastic engine cowel off and de-grass it (3 screws).

You can stop grass getting in from the crank case side by modding it, see

Outerwears make pullstart covers, but they are rather expensive for what you want them to do (you only need to stop grass and stones, dust isn't an issue in the pullstart cover). Alternative answers are in the below links, a cheaper version of an outerwears filter, and a supercheap version....

If on the other hand you ran without an air filter and grass/dust went through the carb, prepare for a good disassemble and clean, or even rebuild.

You don't have to take the head off or anything complex.

You only need to take three ecrews out of the black plastic top cover, one on the clutch side, two at the top on the fan cover side (and probably also take the spark plug out). You can then unclip the plastic cowel from the top of the engine. You should then be able to get the majority of grass out with a pair of needle nose pliers or small allen key. So long as the spark plug hole is covered, you can also give a few tugs on the starter to blow any grass out of the fan case.

But if the head looks more like a hay bale than an engine, you can also take the fan cover off (2 hex head bolts and 2 nyloc nuts) to give it a propper clean. But this isn't allways neeed. Either way, you should not need to open up the engine itself (unless you were daft enough to run without an air filter!)


If you do remove the spark plug, do not let anything fall into the engine.



I can do you some images of the screws to remove this evening if you still need help.

Blow it out with an air compressor. You should be able to remove 99% of the debris with a good air compressor. don't remove the filter or spark plug when cleaning....

+1 BTB, do you run with a body on? This should stop allot of grass getting inthere.

The crankcase mod can be a bit daunting when new to rc but take it slow and it really is quite easy. I got help with mine for the first time and never had a blade of grass enter in/around engine since, really is worth it time wise because you will spend much longer in the long run removing the cowl and taking the grass out that way.

pull start cover from hongkong much cheaper than outerwares and does the same job i have got two of these and they work just fine

Yes it CAN damage the engine
If you get enough in , it can overheat the engine and the piston will melt to the head and stop dead.
